Embodiment Construction

[0043] Figure 1 to Figure 6B Different views of an embodiment of a vacuum cleaner 1 according to the invention are shown. The vacuum cleaner 1 comprises a housing 2 provided with an air inlet 3 , a first chamber 4 , a second chamber 5 and an air outlet 6 . The air inlet 3 is located at the bottom of the first chamber 4 and the air outlet 6 is located in the wall of the second chamber 5 . A wall 7 is located between the first chamber 4 and the second chamber 5 . The vacuum cleaner 1 is also provided with a vacuum fan 8 in the second chamber 5 and a centrifugal fan 9 in the first chamber 4 . The vacuum fan 8 and the centrifugal fan 9 are connected to each other by a hollow tube 10 extending through the wall 7 . The vacuum fan 8 and the centrifugal fan 9 can be rotated together about an axis of rotation 11 by means of an electric motor 12 . Air will enter the centrifugal fan 9 through the air inlet opening 109 and leave the vacuum fan 8 close to the air outlet 6 . The elect...

Abstract

A vacuum cleaner (1, 21, 31) comprises an air inlet opening (3), an air outlet opening (6) and a rotatable separator (9) for separating air and airborne particles. The separator (9) comprises at least one air entrance opening (109) located between the air inlet opening (3) and the air outlet opening (6). The vacuum cleaner (1, 21, 31) is provided with air-guide means (15, 22, 37) for guiding at least part of the air towards the separator (9). In use, the air- guide means (15, 22, 37) provides an at least partially closed boundary in axial direction for a column of rotating air (17) around the separator (9). The minimum distance (Rag) of an edge (115, 122) of the air-guide means (15, 22, 37) to the rotating axis (11) of the separator (9) is larger than a distance (Rs) of the air entrance opening (109) of the separator (9) to the rotating axis (11) of the separator (9).

Description

technical field [0001] The present invention relates to a vacuum cleaner comprising an air inlet, an air outlet, a chamber and a rotatable separator for separating air from particles in the air, said separator comprising at least An air enters the opening. Background technique [0002] In the vacuum cleaner known from International Patent Publication WO 92 / 03210 A1, air contaminated with airborne particles such as liquids, dust and dirt is moved towards a separator by means of a vacuum. As the separator rotates, centrifugal force acts on the airborne particles, thereby removing the airborne particles from the separator, while clean air flows through the separator to the air outlet. Relatively heavy particles will be separated from the air at relatively low separator speeds. However, relatively high rotational speeds are required in order to be able to separate relatively light particles as well. At such relatively high rotational speeds, heavier particles may move in the ...
